“Ryan and Jethá tell us (p. 206) about a study of the Waorani of Ecuador which showed that they were free of most diseases and had no evidence of health problems such as hypertension, heart disease, or cancer (Larrick et al.1979).What they don’t add is that Larrick and his colleagues found that 42% of all population losses were actually caused by Waorani killing other Waorani.”

“That was the worst part about having cancer, sometimes: The physical evidence of disease separates you from other people.”

“I believe that human beings are designed to be physically active and that not doing so creates energy imbalances within the body that ultimately contribute to obesity and other health problems. As evidence, over 500,000 people die each year from diseases linked to physical inactivity and obesity. Furthermore, rates of hypertension, hypercholesterolemia, type 2 diabetes, and certain forms of cancer have all tripled over the past 30 years corresponding to decreasing levels of daily physical activity and increasing rates of obesity.”

“After hearing much from his patients about alleged faith-healing, a Minnesota physician named William Nolen spent a year and a half trying to track down the most striking cases. Was there clear medical evidence that the disease was really present before the ‘cure’? If so, had the disease actually disappeared after the cure, or did we just have the healer’s or the patient’s say-so? He uncovered many cases of fraud, including the first exposure in America of ‘psychic surgery’. But he found not one instance of cure of any serious organic (non-psychogenic) disease. There were no cases where gallstones or rheumatoid arthritis, say, were cured, much less cancer or cardiovascular disease. When a child’s spleen is ruptured, Nolen noted, perform a simple surgical operation and the child is completely better. But take that child to a faith-healer and she’s dead in a day.”

“Don’t ask a writer what he’s working on. It’s like asking someone with cancer on the progress of his disease.”

“The simplest way to look at all these associations, between obesity, heart disease, type 2 diabetes, metabolic syndrome, cancer, and Alzheimer's (not to mention the other the conditions that also associate with obesity and diabetes, such as gout, asthma, and fatty liver disease), is that what makes us fat - the quality and quantity of carbohydrates we consume - also makes us sick.”
